Eight strands, each in Seale construction 1-9-9
8x7-WSC - Independent wire rope core made of 8 strands in (1-6) construction closed around a center strand in Warrington construction (1-6-6+6).
1570/1770 (extra high strength)
Dual tensile, outer wires: 1570 N/mm², inner wires 1770 N/mm².
Right ordinary lay (Right regular lay)
10 to 22 mm ( 3/8 " to 7/8").
Properties & applications:Elevator rope. The addition of steel strands to the core increases the metallic cross section and so increases the breaking force and decreases the elastic elongation (stretch) of the rope under load. Similar to ropes with combined core but with higher breaking force and lower elongation. Used on traction drive elevators, especially on high rise installations, high speeds or where the ropes pass over many deflection sheaves.
Information for use and maintenance:Rope Category Number (RCN): 04 Rope ends must be secured against rotation.
